I recently got a Smoothieboard 5xC and planning to use the Viki2 Panel, however I am having hard time figuring out the wiring. I read everything I could find in the web and this forum related to this topic but could not find the answers to my questions.
Viki2 wiring is different between 4xC and 5xC. In the documentation we can see the configuration for both, however the wiring is just for 4xC.
I am trying to figure out the wiring for the 5xC based on the documentation, however I have some questions that I can’t find the answer anywhere.
PS : I am not using an external 5V power supply or a USB cable to provide the 5V. I decided to go with the Recom part R+78E5.0+1.0 to power the board from the main power supply (24v in my case).
I have four main questions :
4xC uses pins 1.31, 1.22 and 1.23 for buzz, red led and blue led respectively. You can see it in the configuration and in the wiring as well, they match.
5xC does not use buzz or blue led in the config (commented), just the red led mapped to pin 1.31
Should My wiring be ?
Buzz : Not Connected
Blue-LED : Not Connected
Red-LED : pin 1.31
I imagine the answer is yes based on “5 driver smoothieboard, disables buzzer and uses red led instead”, however nothing was said about the Blue led. Should I still use it and uncomment the Blue Led line in the config for the 5xC version or not use the blue led at all?
On 4xC config we have :
panel.external_sd.spi_cs_pin 2.8 # set spi chip select for the sdcard (NOTE 5 drvier can't use this) panel.external_sd.sdcd_pin 2.13!^ # sd detect signal (set to nc if no sdcard detect) (NOTE 5 drvier can't use this)
SDCS to P2.8
SDCD to P0.27
Looks like SDCD in the config and the wiring does not match. Is it supposed to be this way ?
On 5xC config we have :
panel.external_sd.spi_cs_pin 0.27 # set spi chip select for the sdcard panel.external_sd.sdcd_pin 0.28!^ # sd detect signal (set to nc if no sdcard detect)
How should I wire these two on 5xC ? Is the 4xC config and wiring correct for these two ?
Like I mentioned before, I am not using 5V input (using Recom part R+78E5.0+1.0). Where should I connect the Vin (5V) and GND from Viki2 on the 5xC ?
I think i know this one, but just want to confirm. Do I need anything else to connect the Viki2 Panel to the Smoothieboard 5xC ? Do I need any shield or any other controller ? I believe the answer is no, I don't need anything else. I just want to double check before i lock on a panel decision.
Thank you for the help really appreciate it.
